About this Mod

title


Client-side mod that improves performance by intelligently hiding (culling) distant entities and block entities that are not visible to the player.
It’s simple, optimized, and works seamlessly with most visual mods and shaders.

How It Works

The mod skips rendering of objects beyond a configurable distance, saving resources and boosting FPS.
Each object type (mobs, boats, signs, item frames, etc.) can have its own render distance.
Key visual elements remain visible within reasonable ranges to preserve the game’s look.

Features

  • Optimized culling algorithm with minimal performance impact.
  • Separate distance settings for different object categories.
  • Display entity support (Item Display, Block Display, Text Display).
  • Full shader and render mod compatibility.

Known Issues

Signs will not be culled if Enhanced Block Entities is installed with sign culling enabled, because it uses baked models for signs.


Requires oωo and TLib to work.

Frequently Asked Questions

Does Culler need to be installed on the Minecraft server?

No. Modrinth marks Culler as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Culler require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.10, 1.21.9, 1.21.8. Files for different loaders are not interchangeable.

Culler is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
